PRODUCT DATA SHEET
Mexel®432 Performance Emulsion.
Mexel®432 is a proprietary filming polyamine that acts as a surface-active agent (surfactant). Unlike bulk water treatments, it functions by adsorbing onto system surfaces to create a monomolecular barrier against biofouling, corrosion, and scale.
Technical specifications and application data.
Mechanism of Action
Mexel®432 operates via Surface Interface Activity rather than bulk water chemistry modification.
Dispersant Action
Prevents suspended solids and biological matter from adhering to tube surfaces/plates.
Corrosion Inhibition
Forms a hydrophobic film (migrating to the cathode) that isolates metal from oxygen/water contact.
Scale Prevention
Distorts crystal lattice formation, preventing hard calcite/silica deposits from bonding.
Automated Dosing Hardware.
Precision control is the difference between "chemical dumping" and engineering. Our skid-mounted systems use active feedback loops to maintain exact concentrations, minimizing chemical use while guaranteeing performance.
Smart Controller Architecture
- ✔ Raspberry Pi 4B + Arduino MKR WiFi logic
- ✔ Local MySQL database with Cloud Replication
- ✔ Integrated GSM Router for remote telemetry
- ✔ Ultrasonic Level Sensors (Auto-cutoff protection)

Application & Dosing Protocols
Mexel®432 is applied via pulsed dosing rather than continuous feed, targeting the surface interface specifically while minimizing chemical consumption.
Typical Dosing Parameters
| System Type | Dosing Rate |
|---|---|
| Once-Through (Power Station) | 3-5 ppm, 20-30 min/day |
| Recirculating Cooling Tower | 5-8 ppm, 2-3 pulses/day |
| Closed Loop (HVAC) | 10-15 ppm, weekly maintenance |
TES IoT Integration
Automated Dosing Skid
TES Thingy:91 skid controls dosing timing and volume precisely, logging all events to the cloud for compliance.
Compatibility
Can be integrated with existing anti-scalants if required, though Mexel®432 typically replaces multi-product programs.
No Shutdown Required
Installation is a simple tap-in to the cooling water inlet. Cleaning happens entirely while the unit runs.

Environmental Profile
Biodegradability
Mexel®432 is readily biodegradable. It naturally degrades in the water column within 24-48 hours, leaving no persistent residue.
Toxicity (LC50)
At recommended dosing concentrations (e.g., 5ppm for 30 mins/day), the discharge load is significantly below acute toxicity thresholds for aquatic life.
*Always refer to the latest Safety Data Sheet (SDS) for site-specific compliance.
Performance Validation Data
Mexel®432 performance is validated using ASME PTC 12.2 methodology, ensuring that MW gains are engineering-grade measurements, not estimates.
TTD Reduction
2-4°C
Typical Terminal Temperature Difference improvement during intervention phase
Vacuum Improvement
5-15 kPa
Condenser back-pressure reduction at matched load conditions
Heat Rate Recovery
1-3%
Station heat rate improvement translating to MW capacity restoration
Why Mexel®432 vs. Traditional Chemicals
Mexel®432 represents a fundamental shift from "slash and burn" oxidizing biocides to a surface-active, film-forming approach.
| Criteria | Mexel®432 (TES) | Traditional Biocides |
|---|---|---|
| Dosing Frequency | Pulsed (20-30 min/day) | Continuous or frequent shock |
| Chemical Consumption | 90% reduction vs. continuous | High volume required |
| Environmental Impact | Biodegradable, non-toxic | Persistent, aquatic toxicity |
| Corrosion Protection | Active film-forming inhibitor | None (can accelerate corrosion) |
| Scale Prevention | Crystal lattice distortion | Requires separate anti-scalant |

Technical FAQ
Common questions from station engineers and chemists.
Does Mexel®432 work with seawater?
Yes. Mexel®432 has been successfully deployed in seawater cooling systems (desalination, coastal power stations). It prevents marine fouling without environmental harm.
Is it compatible with Admiralty Brass tubes?
Yes. Mexel®432 is compatible with all common condenser tube metallurgies including Admiralty Brass, Titanium, Stainless Steel, and Copper-Nickel alloys.
What if TTD doesn't improve after dosing?
High TTD is not always fouling. Our verification protocol includes a baseline phase to rule out non-fouling issues (air ingress, passing valves, mechanical problems) before dosing begins.
Can I use it alongside my existing anti-scalant?
Mexel®432 typically replaces both biocides and anti-scalants. However, it can be integrated with certain programs if required. Contact our engineering team for compatibility assessment.
How quickly will I see results?
Measurable TTD improvement typically appears within 2-4 weeks of intervention. The full cleaning effect depends on the severity of existing fouling.
